Penta Prisms are used to define right angles in optical systems. Penta Prisms, which provide right handed images, feature a ray deviation of 90°. Penta Prisms are five-sided prisms and unaffected by slight movements. Edmund Optics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums. The Penta Prism will neither invert nor reverse the image. Penta prisms are extremely useful in alignment systems as they define a right angle very precisely and independently of angle of incidence. Rays entering one face emerge from the adjacent face at precisely 90 deg after they have undergone two reflections inside the prism for a total of 270 deg. The penta prism acts as a turning mirror which is insensitive to alignment.

It is used to separate light or cause the beam to be dispersive, and the material is usually glass, crystal, etc. It is widely used in optical instruments. Classification of Optical Prism According to the uses of optical prisms , it can be divided into: 1. Deviation optical prism: let light change direction through a prism, and generally a prism less inclined is called a wedge or thin prism, the achromatic Fresnel biprism can also be used for deflection(no dispersion). 2.Dispersive prism: the refractive prism of a large Angle, mainly used in spectral instruments, the main function is in refraction. 3.Reflecting prism occupies a significant position in the non-dispersive prism, it can change the direction of the light as well as the image shift. It is usually used to reduce the light consumption with full reflection. 4. Polarizing prism: to separate polarized light from non-polarized light, it is used to study some physical phenomena of polarization or to control the strong light. 5.In the microscope, a prism is also used to complement the light. Uses of Optical Prism Optical prisms play many different roles in optics, and the combination of prism can be used as a beam splitter, a deflector, etc. But in most applications, only the dispersive function of the prism is used, or to change the direction of the image and the direction of beam propagation. The function of dispersion makes the prism an excellent dispersive element, the role of the prism plays in the spectrometer, spectrograph and monochromator. In many optical instruments, the prism is oft
